I would just change up the routine to incorporate other muscles. Do legs one day and then switch to upper body the next and then switch to something aerobic the next day.
Look on line for exercises that use different muscles so your not stuck using the same ones every day.

Continue to do your basic exercises: sit-ups and push-ups daily, slowly adding more reps always aiming for a place just before muscle failure. Add to your daily exercises with chin-ups/pull-ups dipps, roll-outs and ball exercises (targeting your weak areas). Each day after you finish your basic exercises do 30 to 60 minutes of vigorous aerobic activities like: cycling, or running, or swimming. Once a week do weight training. Eat a healthy diet as recommended by the National Institute of Health (NIH) and aviod junk foods, tobacco, alcohol and other drugs. Get adequate sleep. If you feel tired and or sore then take that day off. Keep an exercise journal and log all activities including sets and reps so that you can chart your progress. This basic plan has worked well for me. It takes a lot of hard work in order to maintain good health and fitness. That is why most adults are in such poor health and that is so sad. The late Dr. George Sheehan said “We are all athletes. It is just that some of us are in training and some of us aren’t”. Good health to you!

If you are serious about a good overall routine, just find yourself a good trainer in your area. Invest a couple hundred dollars in having him/her train you for a few sessions and help you come up with something that works for you. Then go back to get a refresher workout every 6–8 weeks.
The time and money spent will save you from making mistakes, wasting your time, or hurting yourself in the future.
